Other objects and advantages of the invention will appear as this description proceeds.

Referring now to the drawings, Figure 1 is a side elevational view of a chair, with my attachment mounted upon it.

Figure 2 is a front elevational view of the chair, also having the attachment upon it.

Figure 3 is a cross-sectional view along the lines 3--3 of Figure 1.

igure 4 is a cross-sectional view of a cuff ment, whereby the attachment is secured leg member.

Figure 5 is an inside elevational view of the front portion of one of the arms in my attachment.

igure 6 is an inside elevational view of the horizontal portion of one of the arms in my attachment.

arrangeonto the chair The bent is mounted on said chair. end portions 10, 10a and 11 of each of said arms are leg members (in the not be interfered with by seat cushion 6.
